When Should I Replace My Hyundai Serpentine Belt? Most serpentine belts last for 50,000 miles or more. Consult your Hyundai owner's manual for details on your specific vehicle. Symptoms that point to a failing serpentine belt generally appear as poor performance from accessories, rather than driving performance.

If the belt is wobbling back and forth or the pulley is not spinning straight and wobbling, the pulley may be misaligned, which can cause the belt to squeal. Also, check if the belt is running in the center of the pulley and is not running off to the side.

Replacing the serpentine belt is as simple as threading it into position, cranking the tensioner and slipping the belt over the tensioner pulley, or nearest pulley up top. Belt tensioners are mostly spring tension. Once installed, the spring retains pressure to the belt.

That is why it's so important to stay ahead on your car service and get your belt replaced before it completely breaks.

Look for cracks, fraying, or splits on the top cover. Look for signs of glazing on the belt's sides. Glazed or slick belts can slip, overheat, or crack. Twist a serpentine belt to look for separating layers, cracks, or missing chunks of the grooves on the underside.

What else should be replaced when replacing serpentine belt? ›

In addition to the belt itself needing to be periodically replaced, the tensioner pulley (and the idler pulley, if there is one) spins on bearings, and over time, they wear out.

Since the serpentine belt helps provide power to cool the engine, a faulty belt can cause the car engine to overheat as the water pump will not turn. As soon as the engine begins to overheat, have it inspected by a mechanic as it can cause a breakdown and cause engine damage if left overheated.

You spot visual signs of wear: Cracks, splits, and fraying are visual indicators of a worn belt. If the belt's sides are glazed over, the belt won't last much longer.
